(a) In 16-bit 2's complement representation, write down the bit-pattern representing 27, -27, 43 and -43 respectively.

(b) What are the value of the bit pattern if they are treated as unsigned numbers.

(c) Add the bit patterns together for the following: i. 27 + 43 ii. 27 + (-43) iii. (-27) + 43, and iv. (-27) + (-43)

(d) What is the largest (most positive) value and the smallest (most negative) value of a 16-bit 2's complement representation?
